other reviews.....its too small, its too expensive, its too......SIMPLY RETURN FOR REFUND OR EXCHANGE...I am from the North, so I wanted a hat the wind didn't blow through. Also wanted something I could wear to work outside at -20F......This had supersedes all others. YES, exceptionally warm, hot in fact, even at extreme temps. DO NOT BUY if your winters are average. You better be in Arctic conditions to wear this well made hat. Northerners will be amazed at its quality, durability and warmth. YES its itchy if wool is itchy to you. For me, I can take it.....CONCLUSION: Nothing beats wool to keep you warm underneath. It is a hollow fiber and insulates when wet. Dachstein Wool is one step away from being felt, and it keeps the heat, in, and weather, out.A beautifully made hat for extreme low temperatures. Worth every penny!
